This studyattemptedto estimate the technical efficiency and its determinants ofdragon fruit farming, based on the data collected from 118 dragon fruit farming householdss in Chau Thanh district, Long An province. A Cobb-Douglas stochastic frontier model incorporating inefficiency effects was employed to analyze the data using the Frontier 4.1. The results revealed that the technical efficiency rangedbetween 49.5%-97.4 %(76.0%on average).Significant factors that were found to positively affect dragon fruit yield were cultivated area, potash fertilizer, and labor while seed (planted density) was negatively related to the fragon fruit yield. In addition, significant determinants that positively related to technical efficiency were farmers’ education attainment, membership of local associations, technical training and credit access. The improvement of these factors would lead to an increase in technical efficiency.
